Displaying child pages of the current page

A prime feature of most CMS systems is that pages have a strong hierarchy – plenty of pages, sub-pages and sub-sub-sub pages. Depending on exactly what you want to accomplish, there’s a main means of doing this that will help you have a nicely dynamic navigation area.

At first glance

wp_list_pages('title_li=&child_of='.$post->ID);

…would be an option, except that when you end up on a child page, the list disappears because the current page no longer has any children.

Enter the solution:

<?
if(wp_list_pages('child_of='.$post->ID.'&echo=0&exclude=2')) {
echo "<ul>";
wp_list_pages('title_li=&child_of='.$post->ID.'&exclude=2');
echo "</ul>";
}
elseif(get_the_title($post->post_parent) != the_title(' ' , ' ',false)) {
echo "<ul>";
wp_list_pages('child_of='.$post->post_parent.'&title_li=&exclude=2');
echo "</ul>";
} ?>

What this does is:

• Generate a list of sibling pages if there are no child pages present
• If there are child pages, they’ll be shown

This is really useful for creating a dynamic navigation that constantly allows users to move to other pages on the site and will also allow your client or the end user to create pages and sub pages freely without having to worry about digging through code to update the navigation area.
